"Android OS" battery drain, any solution? - Sony Ericsson Xperia Neo, Pro

Hello everyone,
I have big problems with battery drain! When I look into battery in settings I see Android OS causing huge battery drain. I am on stock Ics, tried many things - rooting, changing kernel, uninstalling bloatware with Titanium, changing baseband ... Nothing seems to help! I've realized that Android OS is active while WiFi on... When I switch off WiFi, battery life gets very good (or normal) and Android OS stop draining the battery.
Does somebody have same issue or knows THE solution? Except putting CM9 or other non stock Rom, would like ti keep Sony's Rom.
P.s. My girlfriend's Xperia Ray has the exact same problem!?!

Turning automatic synchronisation off & reducing screen brightness might help

Yeah that's probably syncing problems. But just in case get BetterBatteryStats, let it run for a few hours and post me the logs.

WiFi on always eats far more battery than WiFi off.
If you've turned off all synchronizations already then it's just purely the constant search for the WiFi network and back and forth polling needed to maintain the connection being handled by the Android OS that's eating your battery and I'm afraid that would be perfectly normal then and not something one can fix.

Of course, but as you can see in the post above, what is strange is that when I was out of home (the first 3 hours) with wifi on the battery was doing fine even that the phone was probably searching networks all the time, and since I returned home (last 3-4h) the battery drain started again...
Shouldn't it be opposite? When connected to home wifi it should stop searching for it. So it's probably a sync problem, but whatever I don (Sync on or off) it's the same...

Could also be a clash with your router.....
Try changing channel see if that helps, if not you may be stuck with it or go back to gb

good idea! I'll try it, hope it works...

Get BetterBatteryStats somewhere from XDA (google it) start the app, leave your phone for a few hours and then go back into the app, press the settings key on your phone and choose dump to file. A .txt file will appear in the root of your sd card, attach the file to a post. Hope I can help

here it is, but seems have worked only 7h, while I was not home connected to Wi-Fi , so I'll post once more tomorrow...

Well judging by this it might actually be normal for android os to consume as much battery, because you haven't really used your phone much. The battery drain you are seeing on the battery settings is simply android os is draining the most out of your phone relative to other processes using much less.

Thanks to everybody, especially @mpiekp! Finally it seems that Wi-Fi router channel was the problem, since I changed it Android OS stopped, I can see in battery stats that it wasn't active since. The same for my girlfriend's Xperia Ray!
I'll be checking it from time to time in the next couple of days, just to be sure...
I love XDA!

Keep WIFI on during sleep

I've been try to extend the life of my battery, and one of the things I have done is set the SETTINGS/WIFI/ADVANCED "keep WIFI on during sleep" to "never".
I make this change, but most times when I go back into the settings later on, it's changed back to "Always"
Anybody offer a clue as to why this might be happening?
Thanks.

no idea mate it shouldn't do as i have mine set to never and it stays like that, have you been flashing ROM's or anything like that maybe that could explain it!
No, not really.
The only thing I've done is rooted it. Apart from that, It's still got stock Samsung Rom on it.
Just checked again, and even tried setting it to "only when plugged in, but after 15 mins or so, it's back to "always" again.

For anyone else who might come across the same issue.
After doing a factory reset, and putting apps back on one at a time, I found out it was DoubleTwist Airsync, that was changing the "WIFI sleep" option.
Apparently, the developer knows this, but wants it to work that way.
So it's now gone for me
But you won't lose too much battery on an 7 hr sleep with the always on setting.
I go to sleep with my S3 on 98% and wake up with 92-94% battery left even with received messages from 3 email accounts and other notifications.
<------------------------------->

I keep mine on always. I lose 3% during an 8hr sleep and it'll automatically connect to my carrier data when my network is not in range. Sure beats turning it off and on a handful times a day.
Weird is that WiFi is active in either option you shoose during sleep. Even if you choose NEVER, open your battery use stats and you'll see that WiFi was active all the time during sleep. I cannot understand why is this issue so underrated here on XDA forums. Or is it some kind of misinterpreting from my side???

Yup afaik, choosing never will produce a wakelock to check the phone state and keeping it on will cause it to constantly scan even if connected to a network. Both choices will eat up battery.
I see many threads suggesting to just manually turn it off, preventing scanning, wakelocks and syncing all together.

So it is normal that if i choose Never in wifi sleep policy phone, i find the wifi always on in battery stats? This question is not so clear...
Is there any explanation of wifi toggles by author... Google?

[Q] Phone turns itself off

Hi,
When I turn data on, after about 1 minute, the phone shuts itself off.
Is it a kernel, software or battery issue? Happened on X10Sv9 and on Donut's (Ferakernel and DoomKernel).

Does it shutdown when data is turned on directly after you install the ROM and Kernel and before you install and modify your user environment???
Have you configured your APN details?
Using xReccovery you could backup your phone and then step through the process of installing your environment; with xrecovery backups along the way.
Then when you identify the process/application/configuration causing the problem you can restore the previous backup and start from there.
Does this happen when you use a standard SEUS fresh install with no modifications???
Does this only happen when you install an overlocked/modified Kernel????

As far as I can notice, as soon as I use data, camera, or any other, lets say 'heavy' stuff, it turns itself off. If it occurs 2-4 times, the battery starts showing 1%, and then it begins going up till about the previous percentage.

I had exactly the same issue. I didn't use data so.much, but the phone started to shutting down even on 50%. I continued using it and it was definitely battery issue. The battery got bigger, so i couldn't close the back anymore. I have bought a bew one and everything came back to normal behavior .

For WiFi I use an app from the play store called REGPON wifi KeepAlive and it solved the problem for me. I don't have any problem with mobile data connection.
Android has a built in wifi sleep policy, but not every phone backend allows you to modify it. If your device is rooted, you can try an app such as Spare Parts+ from the Play store, it has an option to set your sleep policy. I have used it on several devices, my One X+ included.

Now that I am rooted I am trying the method in that thread, so far it is working and is better than using an app to do it.
REGPON works like a charm, and I am unrooted.
I think that thread deals with it going to sleep between 12-7am whereas my problem was EVERYTIME the screen turned off when I turn the screen back on it will reconnect.
I have NOT had a problem since I switched to REGPON.

Just a follow up to this, WiFi still dropped so back to REGPON WiFi Keep Alive for me.
unfortunately , REGPON is not helping .. still the signal drop off .. but less frequently i would say
Any new solutions for this?
It's extremly annoying!
I tried:
1. Regpon
2. that nice trick, by deactivating smartsync at all with system tools ()
3. Smartsync disabler [APP]
4. Spare parts [APP]
5. Terminal Emulator
There has to be a solution for that.
I would like to keep this topic up, until there comes up a working solution
Thanks.

BUGS in Jelly Bean (P760-V20B)

I know this might sound odd to some of you, but i was doing some heavy use on my phone, and i noticed somethings that happen most of the time but not always, and here they are:
_when playing music via LG's music player, the music stops (sometimes) when hitting power button in order to lock the screen.
_Tapping on youtube and playstore links on the stock browser (modified by LG) takes you always to the mobile site for youtube and not to the youtube app. the same thing with playstore links, it doesn't ask yo if you want to open it in playstore app, but it takes you to the website. i know all about the default actions but believe me, i know what i'm saying. because this doesn't happen using Chrome.
I noticed, that when i'm using google now's voice actions, it doesn't give voice feedback. (even when i set it to us english)

Did not noticed both. Both work perfect. See if there are any default program settings and correct it.
The only problem I noticed is , it takes media scan after each file operation I do. Sometimes it does after boot.

Agreed if you say "bad" but disagree if you say "completely bad". Actually companies dont release roms if they are bad.
Try to do some investigation and find the reason for drain when wifi is on.
I must have 4 Gmail accounts setup with Auto sync. Every 10/20 minutes I get notification sound saying "I've got mail" on "WiFi" which is "ON" all the time in office and home (total 8+ hours)). But I did not notice the drastic drop in battery level. I still get 24 hours in around 60-70% juice.
Like zanakorus33 said you must check which "unknown" and "unwanted" apps are squeezing too much juice from battery while WiFi is on and disable them.
In fact "WIFI" does not drain your battery. Its various app, which get activated when WiFi gets on and try to connect internet for syncing.
PS: Just flashed P765 CIS JB rom and experimenting, else I would post some screenshot too, which I always do.
R: BUGS in Jelly Bean (P760-V20B)
You can think what you want, it's not my problem. Please dont say things about app, drain app, app that draining etc. etc.. i know this stuff very well.
I say this:
with SAME APPS, SAME APPS, FEW APPS with ICS i can do 1 day and half, with JB not.
JB drain battery more than ics, in particualr when wifi is on.
In standby with wifi on in ics.. ... i have already explain in previous post...

At night, I prefer to automatically shut off all radio (wifi, datasync, bt, gps, etc and silent mode), with smart profiles free, except Phone network. Calls and incoming sms still working. Before I wake up in morning all gets started automatically.
I think I dont need wifi, datasync, etc, while I need to sleep. And also have habit to manually start and stop wifi when I need it or not. Maybe this saves some battery for me. In office, wifi mostly on. Everyone have their own ways and preferences, hence different results.
Picture quality has reduced after upgrading to Jelly Bean. I've checked all the camera settings but still pictures a little washed out. Pictures looked better on ICS rom.
Is it me or anyone else also have this problem?

As others have said battery life is slightly worse on JB. For me with 3G and syncing on I could make three before going down to 5% battery (about 33% percent per day), now I have 50% per day. Of course it's highly dependent on usage, talk time, etc.
I have anoying thing on JB P760 V20C.
When I switch off airplane mode and Wi-Fi tries to connect to my home network, some window popups for a fraction of second, like my home net is not available and JB asking me to choose other net (of course the window disappears so fast that I can't really tell if it is really what I suspect).
The same scenario worked flawless on ICS (no popup window).

[CM11] / [KitKat] [4.4] WiFi disconnected bug

Hello everyone,
I'm a cm11 user and since kitkat came out I updated to it.
As everyone know, some if not all devices running kitkat have this problem.
Nobody seemed to fix it so in this thread I'll try to find and share here all the info about this problem and, if possible, will try to keep the thread updates with the possible fix found in the net.
Now I'm with my smartphone, when I'll be back home this evening I'll post the solution that didn't work or worked for a bit.
If anyone knows some possible solution and wants to share is free to do it here, I'll add it to the OP.
About the bug:
The WiFi works for a brief period of time. After that, without disconnecting, or giving any sign of instability it just loses the internet connection.
To fix it you have to turn WiFi off or restart the phone. After some minute the phone does the same thing , finishing into an endless loop.
Thanks for reading.
Balino.

Another thing that made it "more stable" is been reducing the refresh rate in build prop from 150 to 45( cm7 fixed value but it's ok on kk).
This could cause battery drain. Not really noticed the impact on battery life anyway
